To provide top-notch image quality, IP816A-HP also comes with a P-iris lens, which controls the iris with extreme precision with its built-in stepper motor. Controlled by advanced software, the lens maintains the iris opening at an optimal level at all times, resulting in superior sharpness and depth of field. VIVOTEK knows that accurately focusing a megapixel network camera can be difficult due to the level of image detail. In order to help installers properly adjust the focus of this high resolution camera, the IP816A-HP is also equipped with VIVOTEK’s RBF (Remote Back Focus) System, allowing installers to adjust focus even more accurately.
